I am ready to pull this Quadrajet out and go with edelbrock carb. I want a carb that will work well with existing 305 small block, but that will also work with 350 engine, which i plan on putting in later on. Ideas, suggestions? Also, will adapter/s be needed? Is there a how to somewhere for this? Thanks all.

Oh boy.
First you being a CA resident does the car need to pass emission? CA is maybe the hardest place in the world to drive a old car today.

Second the swap to a Edel carb requires a adapter spacer to bolt it to the speadbore intake manifold.

This will raise the carb up about 3/4". Air cleaner to hood clearance decreased, carb linkage also effected.
The 200R trans is very picky about the proper TV cable adjustment. Previous experience with a Edel Performer and a 200R was not good. Put a Qjet back on that engine to have the 200R shift properly.

Several of us will say the stock carb will perform better than the Edel and get better mileage. The stock CCC carb and ECM is not a terrible thing, just needs to be maintained. Out in CA you have the Carb Shop, http://customcarbs.com/ that can freshen a CCC carb for less than the misery of dealing with the Edel carb swap.

I was looking into this as well. I watched a special on Motortrend and they compared an Edelbrock, Summit, and Demon carb. They put them all on a dyno to compare. They were all the 600 cfm models. The Summit was the winner in terms of performance. I also read all the reviews and they are really positive and almost all said the Summit is set up great out of the box needing relatively little adjust once installed. You might need to adjust the idle but not much. It also comes with a dvd to show you how to tune the carb. I did read if installed in your car a kickdown stud is needed but Summit could answer that question if you go that route. This carb will work on a 350 as well. You might was well get a new intake as well which would work with a 350 as well.

What is the reasoning for doing away with the quadrajet ccc? The ccc will support a 350. I think you could save yourself quite bit of money by reading up on these carbs. I think between Doug Roes book and the gm shop manual for our cars it tells you everything you need to know to set one up. Also tons of info on them here and 3rdgen.org. Get your parts from Cliffs high performance his book is good also but doesn't touch on the ccc any. Also a dwell meter. The learning curve at first seems steep but once you dig in they are pretty simple for the most part. In my opinion they are good and once a person learns them are as good if not better than the carbs listed above. Just my 2 cents. Once I get to a point where I want to do away with the ccc I still plan on sticking with a quadrajet.

There is no better carb for your car than the Quadrajet, since you are unhappy with it and most likely don't know how to fix it, I use and recommend www.customrebuiltcarbs.com , at least click on my link and give them a call!!

Stay with the CCC Qjet, its the only legal carburetor for these cars. Here is a link to factory service videos for CCC Qjets.
https://gbodyforum.com/threads/gm-ccc-service-videos.76761/

If you want to hop up the CCC system, upgrade to a heated O2 sensor and get one of Bitflipper's ZZ4 PROM chips. Aftermarket carbs are a waste of money for street cars.

Thanks all for comments. I am in county where smog is not required. I have the edelbrock 600 cfm performance series with 1405 indentifier. Im2 going to give it a try. If all fails ill put back the Qjet after getting it tuned up.

I have the 700R transmission. I understand i need throttle cable bracket or kick down bracket for edelbrock? Any feedback on that. Thanks about info on spacer.

Forget the Eddy and keep the Qjet. Aftermarket carbs are a waste of money. Going non E4ME Qjet is opening a can of worms.

I called both shops listed. The one out in New Jersey costs $350 to get carburetor done. The one in California is $250 and they will run it on an engine before sending it back. So i have that plan to consider if i go back to the Qjet. I think i might want to just order the tools required instead, like the dwell meter and see if i can mess with it. Lots of info and videos here. Thanks all.

I agree with Buick Runner. I have a 383 with the original carb ( was sent to SMI) and the car runs great with no issues.

Franz, couple questions again. Has a 700Rr replaced the TH350 in your 85?
Are you aware that if you delete the CCC setup in the car a few other things need to be changed out?

So living in CA in a county that doesn't need to have emission done on your 85, wasn't aware of exceptions to emissions in CA. Learn something every day.

If you dump the CCC carb you will need another dist to replace the CCC dist on the engine.
Also converter lockup will need to be addressed.
If you change the intake manifold would will need to toss the factory bracket for the throttle cable and TV cable and add another bracket to the rear carb bolts.

The 700R like a 200R requires a TV connection at the carb to work properly and not destroy the trans. Here's a kit from Bowtie Overdrive that MAY adapt another Edel carb to the TV linkage. Pricey.
http://www.bowtieoverdrives.com/catalog/catalog_inc/viewitem.php?ITEMID=213

This is what Edel sells for the Performer carb using a 700 or 200R.
https://www.edelbrock.com/gm-transm...2004r-700r4-4l60-transmissions-8026.html

Not sure how well either of them work when adapting that carb.

Here is lots of info on the TV linkage requirements.
